Recommendations for AR rail covers

[OCB]

I have a Troy quad rail, and so far only have a forward vertical grip and a sling attachment point mounted to it. I've been looking at various rail covering systems from Knight's armament, Troy, Magpul, etc., and I was wondering if anyone had any recommendations or cautionary tales. Has anyone used the cut-to-length systems? Were you able to make clean cuts that looked decent?
Thanks in advance for your input.

I like these: http://stores.homestead.com/Laruetactical/Detail.bok?no=362

I also have the Knights Armament rail covers. They work well, but I prefer the XTM panels because of the color options and size.

I have the KAC covers on my rail.

I cut a couple of them straight across with a dremel tool for a custom length that fit with my Tango Down VFG.

They could probaly use some sanding, but I've had no problem with them.

I use the Magpul Ladder Rails. They're rubbery so you get good grip and it doesn't add a lot of bulk to the rails.

How about these from LaRue?

They look like they provide maximum flexibility.
